Many studies in the past decades have focused on low and typical mathematics achievers, yet little is known about children with high mathematics achievement, particularly at a young age. The current study aimed to fill this gap and started from the early work of Krutetskii (1976) as a theoretical lens to study the characteristics of high…

In 2 experiments, college students read a 4-paragraph text on how the human circulatory system works and were instructed to form a mental image of the events described in each paragraph from the perspective of their own body (first-person perspective group) or from the perspective of a fictitious person facing them (third-person perspective…

Rational number understanding is a critical building block for success in more advanced mathematics; however, how rational number magnitudes are conceptualized is not fully understood. In the current study, we used a dual-task working memory (WM) interference paradigm to investigate the dominant type of strategy (i.e., requiring verbal WM…

Asking students to imagine the spatial arrangement of the elements in a scientific text constitutes a learning strategy intended to foster deep processing of the instructional material. Two experiments investigated the effects of mental imagery prompts on learning from scientific text. Students read a computer-based text on the human respiratory…

Representational and transformational visual imagery instructions were manipulated within two passage types (name and occupation), along with no-strategy control instructions for each passage type. Transformational imagery instructions were effective on the more difficult to remember name passages. Representational imagery instructions were not…

Using 146 high school students, this research assessed the effects of aptitude, strategy training, and item characteristics on the strategic processes employed in the performance of spatial visualization tasks. Treatment effects were shown to depend on the subject's aptitude profile and on the characteristics of items. (BS)
